in applying our device to the guidance of perforated note-sheets it is desirable that each perforation. as it passes the tracker-bar region should be in accurate olineinent for perfect registration with the proper trackerbar orifice In. our device Where there is any failure on the part of e. perforation of set of perforations to register accurately with the corresponding tracker-bar orifices one or more of a. plurality of slits or trigger-openings each positioned in the tracker-her out of registration with the tracker-bar ori'lices and on the edge 01" the normal path of the corresponding note-periorzttioi'i and normally cov ered by the inters ces or intervening spaces about the perforsitions Will become exposed, admitting air through the perforations into tubes and mains arranged to operate pneurnntics and set in operation the roll-shitting nicclmnisni connected thereto, thus guiding the sheet in the direction required for perfect registration of the perforation and trackerbur orifices and closure of the slits and connected tubes. 90

The outer edges of note-sheets and other fragile fabrics, even when out straight originally, are subject to so many variations that their use as a uni ig-line for ting mech shn" anisin depending for satisfactory operation on their streightness and regularity is objcctionzihle. They expand or contract with changes of atmospheric conditions, curl or turn from the results of changes in temperature and from frequent win-ling and rewinrh ing, and are n'iore exposed to weer or injury than the interior portions of the paper.

ing-slit back some distance under the edge,

while expansion may seriously interfere with So, too, the curling or fraying of the edges would destroydelicacy of correction and interfere with satisfactory operation in a device which depends u on the outside edges for correction, since viously a curled,- turned,or defective edge will admit air to the slits or trigger-apertures during'normal progress, and thus defeat the obj ect'of the shifting mechanism. These ob- 'ections are obviated in the present invention y deriving the guidance from the intervening paper etween the perforations so positioned as to pass'near the edges of the perforations, which edges being very short and protected by the surrounding paper cannot appreciably curl or turn and are less likely to present irregularities, while the use of a,

number of correction-points insures con- 'stant test and frequent correction. Our invention is also adapted to guide sheets having biased, crooked, or jagged edges Our device has capacity for guiding sheets perforated at any point or points intermediate of the edges, no special alinement, preparation, or arrangement of the perforations thereon being necessary. a

'Inaccuracy in the perforating of note-,

sheets due to divergence of the sheet from its normal'path when being fed to a .musiccutting machine results in a variable margin in relation to the edge of the sheet. Our de vice has capacity for correcting this defect in manufacture.

Further, there isan objection to moving one roll and, adjusting it relative to the other,

rics, to cause the sheet to wrinkle. This difliculty is overcome in the present inven tion by mechanism which alines both rolls simultaneously.

In the accompanying drawings we have shown a device embodying our invention in 45 its preferred form, illustrating its use on self- 'ng musical instruments.

igure 1 is a face view of a frame containing'feed or rewind and take-up or wind rolls and mechanism for shifting them laterally in either direction, the'perforated sheet or web thereon being cut away to reveal the'tracker bar orifices and the slits or trigger-openings operating the shifting mechanism. ,This figure shows the position assumed by the partswhen the sheet is in'its normal path of travel, the approaching perforations being in proper alinement for accurate. registration wit the orifices. Fig. 2 is a similar view of I the trackenbar and adjacent parts, showing the position assumed by a perforation when the sheet is diverted or deflected from its normal path too far to the right, so that the perforation exfposes one of the slits or trigger-' o enings and ails to register accurately with t e corresponding tracker-orifice. Fig. 315

3 a face view of the pneumatics for operating the shifting-rod to adjust the rolls and of the tube connections between the slits or trigger openings and the pneumatics. The pneumatics are here shown in the position assumed when the sheet is traveling in its normal path. Fig. 4 is a front view of the pneumatics, showing the position assumed when the sheet has been deflected from or drawn out of its normal path too far to the right. Fig. 5 is a cross-section of the feed and take-up rolls and trackerbar, showing in perspective the tubes connecting the slits with the-main conduits or pipes to the pneumatics and a tracker-bar orifice with the connecting-tube to sound-producing devices. Fig. 6 is a topview of aportion of the tracker-bar, showing the relative location of the slits and tracker-bar orifices. Fig. 7 is a cross-section on'the line 7 of Fig. 6 Fig. 8 is a similar view taken on'the line 8 of 6.

I) is the tracker-bar, havin the usual orifices 3. Adjacent to these ori ces, but out of alinement with them, are pairs of slits or mouthpieces 6 and 7, 6 opening into tubes 8', communicating through main 11 with collapsible pneumatic 12, and slitsor mouthpieces ,7 into tubes 9, communicating through main with collapsible pneumatic 14. The tracker-tubes and mains are exhausted of air when covered by the sheet by bleeder or exhaust mechanism well known in .this art.

there are spaces between the tracker-bar orifices, though it is obvious that fewer pairs ma be used to advanta e when desired. It-

. wil be'notited that the s its 6 are arranged in 12 the lever 15, loosely embracing the rod 16, rigidly securing the rod 16, the button 17 having cushioned surface or surfaces 18 so pneumatic 12 will cause thelever '15 to contract with it and draw rod 16 from left to right, and similarly attachin to collapsible pneumatic 14 the lever 19, To

Attached to the frame A, Fi 1,are hOI'lzontal supports 20 and 21, ho ding the upright shaft 22. Shaft 22 at its lower end s bent at right angles, and to the end of this positioned that the contraction of collapsible 18 of the buttbn 17, rigidly secured to rod We prefer to provide as many of these slitsas to the right and 7 to the left, and to accom- Y plish this shifting by attaching to pneumaticosely embracing rod 16, adapted, when the pneumatic 14'is col- 'is actuated to move the upper roll C to the tervals across its surface, means for propelbut . for restoring contact between the ducts and tion held out of operation when the perforaleft, arm 2% moves roll B until the collar contacts with spring 27, thus placing the rolls B and C in alinement. Likewise when arm 24 is actuated to move the lower roll B to the right arm 23 moves away from collar 25, allowing spring 28 to move the upper roll C until collar 25 contacts with arm 23, likewise placing the rolls B and G in alinement.

While we have shown and described mechanism. in which the normal relation between the note-perforations and tracker-orifices is maintained or restored by shifting the sheet or web, we do not wish to be understood as limiting our invention to this construction,
